To all whom t may concern.'

Be it known that we, ORAGE PHILIrAHoeBs,

IGAN, citizens of the United States, residing,

respectively','at Royston', -Winder, and Win der, 'inthe counties ofFranklin and Barrow and State of Geer ia, have `invented a uster, ofwhich the following is `a specification.

This invention relates to a machine for applying poisonous powder'tovegetation, such as cotton plants, one of the objects of the inventionbeing to provide a structure of this character in the form ofanattachment for a plow or cult-ivator whereby, during the 'cultivation ofthe rows of plants the powder can be applied thereto for the purpose ofdestroying boll weevils and other insects destructive` vof -plant life.o

A further object isto provide a dustin apparatus which is simpleand'eicient, wi i not readily' get out of order,` and which can beemployed for dusting two or more rows simultaneously. y

Another object is to provide .novel means for controlling the deliveryof th'epowder from the apparatus, it being possible'to use acomparatively small amount over an extensive area.

A still further object is to provide simple means for indicating theamount per acre delivered from the machine when the delivsans is set.

e m rVit'h the foregoing and other objects in view which will appear asthe description proceeds, the invention cons1sts of certain noveldetails of construction and combinations of parts which will behereinafter more fully described and pointed 4out in the claim, it beingunderstood that various changes may be made in the construction and ar`rangement of the parts without departing from the spirit of theinvention as claimed.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawin y Figure 1 is a si e elevation.

Figure2 is a plan view.

Figure 3 is a section on line 3-3, Figure 1.

Figure 4 is .an enlarged section on line 4-4, Figure 3.

Figure 5 a section showing the` outlet of the hopper. Y

'Figure 6 is a sec-tion through the geary housing of the blower.

standards 2 to which the soil engaging shovels'or the like' (not shown),are to be connected. A supporting wheel 3 is journaled 1n the front endof the frame and is provided on one side wlth spaced annular gears =j 4separated by channels ,5. Handles 6 are extended from the'frame 1 andare reinends.

Referring tolthe figures bycharacters of l reference, 1 -designates'theframe of the plow or cultivator provided at Vone end with Detachablymounted onI the sidesfof the frame 1 are standards 11 vwhich support aIhopper 12 the bottom of which has its walls converging to vprovide atransverse trough 13. One side Wall of the hopperhas spaced outletopenings 14' therein and a shaft 1 5 is journaled between these openingsand'also in the opposite side of the hop er. to the shaft 15 so as torotate t erewith is a worm 16 extending longitudinally of the trough 13and located on the shaft at one end of the worm and close to theopenings Secured y14 are one or more `arms 17 4extending racovers a slot23 formed in the vwall of the hopper and has a Wing. or extension 24whereby material can be prevented from leaking through the slot whentheV outlets 14 are closed. A finger 25 is extended from the gate andthrough Slot 23 and has an index or pointer .26 at its outer end whichcooperates with a series of graduations to indicate the number of poundsthat will be distrlbuted to the acre when the gate is set as indivcated.By meansvof this arrangement the adjustment of the outlet openings canbe effected minutely and the discharge of owder can be accuratelycontrolled. (bviously when the shaft 15 is rotated the worm 16 willdirect the'powder inA the `hopper toward the openings )14-th1ough whichit:

will be forced-in quantities dependent upon the size of the exposedportions of the openings. The brushes will prevent the openingsromclogging. Mined to one end v'of the shaft 15 is a sprocket 27 adaptedto receive motion through a. chain 2 8 from a sprocket 29 se-l cured toa shaft v30.l This last mentioned shaft is journaled at one side of theframe 1 and has a beveled gear 31 meshing with a beveled gear 32 securedto a shaft 33. The Aforward end of the shaft has a pin tooth gear 34feathered or otherwise mounted thereon so as to rotate therewith andslide thereon. The gear is ada ted to mesh with an one of the. gears 4an when moved into eit er of the grooves or channels 5 will remainstationary or neutral. A rod 35 is connected to the gear for the purposeof shifting it along the shaft 33 and this rod can be connected toalever 36 mounted on jolie of the handles 6.

Mounted under the hopper 12 is a blower 'casing'37 having an'inlet atthe center of one side thereof as shown at 38. A ue 39 extends to isinlet from the outlet openings 14 so th t material delivered from thehopper 12 will be sucked into the casing 37. Casing 37`has' a tangentialoutlet 40 or, as shown in the drawings, two or even more of theseoutlets can be provided. To each outlet 40, which is in the form of atubular ex-A tension, is *connected a' hose 41 having a nozzle 42 at itsrearend designed to scatter owderbroadcast when delivered therefrom.

achyhse is .engaged and supported by one of theelamps 10. l

A shaft 43 is "ournaled in the blower casing 37 and carries a blower 44.A gear '45 is secured to one end of this shaft and motion is adapted tobe transmitted thereto through a train of gears, 46., from a ar 47 onshaft 30. These gears are prefera ly located in a housing 48 and areadapted to ,The blower 44 will, at the same time, be

driven at ahi h speed and suck into the housing 37 al of the powderdelivered through the o nings 14. This powder will then be ejecte intothe hose 41 and scattered through the nozzles to the adjacent plants. Ithas been found in ractice that-by using an apparatus such as describedan insecticide like powdered calcium arsenate, can be dusted eicientlyover two or more rows of plants. By having a shifting gear 34 themechanism can be operated at a desired speed and! moving the gear ont ofengagement with either of the gears 4 and into one of the channels orgrooves 5 the mechanism can be brought to a stop while the machine isbeing turned or while it is being moved to or from the place of use.

It is to be understood that, if desired, the

vdriving mechanism` can be varied. For example a friction drive could beused instead of that illustrated or chain and s rocket mechanism couldbe used instead o gears for shaft 33. Y

Importance is attached to the particular placing of the hopper which isdirectly over the blower. It has been found in practice that such anarrangement facilitates the free and unobstructed flow of the powder andwill tend to prevent clogging. l

Vhhat is ilamed is e com ination wit a supportin structure includn awheel actuated gearg of an attachment or the structure including ahopper on the structure and ha a side outlet, agate slidably mounted inthe hopper for' controlling the flow of material through the outlet,anindex movable with vthe gate and outside the hopper, there being aslot in the hopper for the index, means for closing the slot, a blowercasing having an inlet and an outlet, means for conductin material fromthe hopper outlet to the iniget of the casing, speed multiplyingmechanism operated by said gear for actuatin the blower inthe casing,and means for` orcing material through the outlet of the hopper.

In testimony that we claim the foregoing as our own, we have heretoaflixed our signatures.
